Amblyopia is commonly known as'lazy eye. It is a vision development disorder, which affects eyes and the brain during infancy and childhood. It signifies that the eye does not achieve a normal visual acuity even with refractive correction in form of glasses or contact lens. During normal visual development, the eye and brain learns to'see' and develop binocularity, that is the ability to perceive depth (stereoacuity). This occurs in the first 8 to 10 years of life. 

Each eye transmits a clear and identical image from retina to the brain, which fuses the two images into a single image with 3 dimensions (adding depth). When the image is formed on the retina of two eyes is too dissimilar, the brain cannot fuse the two images and suppresses the more blurred image. As a result, the worse eye does not learn to'see' and becomes'lazy. This condition is seen in 1-4% of population.

The common causes for dissimilar images or amblyopia are:
1. Misalignment of the eyes or squint: it is the primary reason for amblyopia is misalignment of the eyes. In case, both your eyes are not aimed in the same direction, the image captured by each eye is different, resulting in diplopia. The brain will see from the dominant eye and suppress image from the other eye. Over a prolonged period of time, the eye dissociates from the visual cortex of the brain.

2. Refractive amblyopia:
A. Unequal refractive error in both eye. When the eye power of both eyes differ by more than 1.5d of spherical equivalent, which results in dissimilar images between the two eyes. As a result, the visual development in restricted in the worse eye.
B. High refractive error or astigmatism in both eyes, since there is a blurred image in both eyes, the normal vision development does not occur in either eyes resulting in bilateral lazy eyes.

3. Cloudiness in visual system or visual deprivation amblyopia: any kind of obstruction or cloudiness in the normal visual axis of the eye tissues can lead to amblyopia. Disorder of any kind, which blocks a clear image from being focused blocks the formation of a clear image on your retina. Commonly due to congenital or developmental cataracts or corneal opacities or prolonged closure of one eye in early childhood (drooping of one eyelid, eyelid swelling, patching of one eye).

Treatment for amblyopia
For treatment of amblyopia, a child must be compelled to utilize his affected, weaker eye. This can be done by correction of causative factor such as, treating refractive error with glasses, surgical correction of misalignment of eyes followed by patching and vision therapy, cataract surgery.

Patching or occlusion of the good eye
This is done to force the brain to pay attention to visual input from the worse eye. This allows nerve connections between affected eye and brain to develop due to, which the eye'learns to see. Eye drops such as atropine are also used for blurring the vision of the good eye. Some form of vision therapy may also be required to train both eyes to see together and develop some degree of depth perception.

To be effective, treatment should be implement as early as possible, within the period of normal visual development best within first 8 years of life. Some visual gain has been seen in selected patients up to age of 14 to 18 years. This also highlights the importance of a comprehensive eye examination as a routine in young children.

About Amblyopia or Lazy Eye

You must not let the cold and dry air worsen your asthma symptoms. The air that blows during winter time greatly affects people with sinus and respiratory troubles, and all these factors contribute to worsening asthma attacks.

Menstrual disorders are caused by a variety of factors and affect every woman in a different manner. In most cases, it manifests itself in the form of fluctuations in menstrual flow and irregularity in the monthly cycle. Certain disorders are not too severe and can be easily alleviated. Others are more complicated and require the immediate attention of a gynecologist.

As mentioned, there are different specific causes of different kinds of disorders resulting from a range of factors such as hormone levels, functioning of the central nervous system, health of the uterus, etc. 

Some of the most common causes of menstrual disorders are as follows:

Hormonal imbalance
Fluctuating hormone levels in the body have a direct impact on the menstrual cycle. These fluctuations can be caused by dysfunction in the pituitary gland, thyroid gland or adrenal gland. It can also be a result of malfunction in either or both ovaries and the secretion of hormones originating there.

Anatomic problems
One fourth menstrual disorders are caused by problems of the anatomy. These include various gynecological issues like the presence of uterine fibroids and polyps, reduced uterine contractile strength, adenomyosis (intrusion of uterine tissue into the muscular wall of the uterus), a uterus with an excessively large surface area, and endometrial cancer.

Clotting irregularities
Abnormality in clotting is a cause of heavy menstrual bleeding in women. It leads to exceeding blood loss from minor cuts and gashes and makes one easily prone to bruising. This may also include medical conditions such as thrombocytopenia (platelet dysfunction) and Von Willebrand disease.

Medications and supplements

Miscellaneous factors

It includes conditions such as cervical cancer, ovarian tumors, liver and kidney diseases, uterine infections, extreme psychological stress, obesity, etc. Incidents such as miscarriages and unsuspected pregnancies are also known to cause abnormal menstrual bleeding.

5 Causes of Menstrual Disorders

Being a victim or witnessing a horrific accident or personal assault can leave you shocked and scarred. Sometimes, these conditions last for months and years with memories of the traumatic incident triggering intense emotional and physical responses. This is known as post traumatic stress disorder or PTSD. It is a fairly common anxiety syndrome and can be treated in a number of ways including drugs, exercise and psychotherapy. However, this treatment aims only to control the disorder and there is no known cure for PTSD as yet.

Exercise not only keeps the body fit, but also helps the body release endorphins. Endorphins help fight stress, fear and pain. Thus, exercising helps focus on the body and its movements instead of your fears. It can also help elevate the mood of a person. Low to moderate intensity exercising is ideal for a PTSD patient. Aerobics, pilates, yoga or martial arts like tai chi are known to be effective ways of reducing stress and anxiety in PTSD patients. Breathing exercises like pranayama can also help calm and relax the mind.

Exercise for a PTSD patient should be planned in repetitive sets. This enables the person to slowly master the type of exercise being done and regain control and confidence in himself. It also needs to be predictable so as to avoid triggering a PTSD emotional or physical response. Non competitive exercises are better than competitive exercises as it does not create an opportunity for the person to feel stressed. Exercising and practicing breathing techniques can also help a person analyze himself and his response to stressful situations. By understanding their reactions, a person can slowly bring about changes to handle stress in a better way.

For a PTSD patient, exercise should not be seen as a group activity but as an individual effort to increase self control. Patience is key here both for the patient and the therapist. It is also necessary for the person to have realistic goals from his exercise regimen. An exercise program for PTSD patients also needs to be flexible. In order to meet the needs of a patient, it may need to be changed in accordance to the medication he is under. Small incidents like having a flat tire when cycling can trigger anxiety in a person suffering from PTSD. However, if dealt with correctly, it can bolster confidence in the long run.

Lastly, exercising also helps improve self-image and build confidence which helps a PTSD patient break out of his protective shell and socialize with others.
